Use the Settings > Filtering page to establish basic settings for a variety of filtering features.
Under Bandwidth Optimizer, enter the information needed to filter Internet usage based on available bandwidth. For more information about bandwidth-based filtering, see Using Bandwidth Optimizer to manage bandwidth.
Note 
In Websense Web Security Gateway Anywhere environments, hybrid filtering does not use Bandwidth Optimizer settings. No bandwidth-based restrictions are enforced on requests passing through the hybrid service.
1.
To specify an Internet connection speed, do one of the following:
2.
Enter the default thresholds to use when bandwidth-based filtering is used. Note that when the thresholds are set, but no category or protocol filters enforce bandwidth-base filtering, no bandwidth usage restriction occurs.
*
Network: When total network traffic reaches this percentage of total available bandwidth, start enforcing bandwidth-based filtering, as configured in active filters.
*
Protocol: When traffic for a specific protocol (like HTTP or MSN Messenger) reaches this percentage of total available bandwidth, start restricting access to that protocol, as configured in active filters.
3.
(Websense Web Security Gateway) Content Gateway can collect information about bandwidth consumed by HTTP traffic and protocols that tunnel over HTTP. Specify whether to use this information to enable bandwidth-based filtering of protocols handled by Content Gateway.
Use the General Filtering section to determine how users are filtered when multiple group policies apply, specify keyword search options, and set password override, continue, and quota session behavior.
*
When the option is selected, the policy that applies the most restrictive filtering setting is applied. In other words, if one applicable group policy blocks access to a category and another permits access, the user's request for a site in that category is blocked.
Blocks sites when keywords appear in CGI query strings (after the "?" in a Web address).
Example: search.yahoo.com/search?p=test
Websense software does not search for keywords before the "?" when this is selected.
Blocks sites when keywords appear in the URL. If the requested address contains a CGI query string, Websense software searches for keywords up to the "?".
Blocks sites when keywords appear anywhere in the address. If a CGI query string is present, Websense software searches for keywords both before and after the "?".
Use with caution. Disable keyword blocking turns off all keyword blocking, even if Block keywords is selected in a category filter.
3.
In the Password override timeout field, enter the maximum number of seconds (up to 3600, default 60) that a user can access sites in all categories after selecting password override (see Password override).
4.
In the Continue timeout field, enter the maximum time in seconds (up to 3600, default 60) that a user who clicks Continue can access sites in categories governed by the Confirm action (see Filtering actions).
5.
In the Quota session length field, enter the interval (up to 60 minutes, default 10) during which users can visit sites in quota-limited categories (see Using quota time to limit Internet access).
6.
Enter the Default quota time per day (up to 240 minutes, default 60) for all users.
As you make changes to the quota session length and the default quota time per day, the Default quota sessions per day is calculated and displayed.
Use the Block Messages section to enter the URL or path to the alternative HTML block page you created for the top frame of browser-based block messages (see Creating alternate block messages).
*
Separate pages can be used for the different protocols: FTP, HTTP (including HTTPS), and Gopher.
*
In Websense Web Security Gateway Anywhere environments, custom block messages are not applied to hybrid filtering requests.
Under Search Filtering, select Enable search filtering to have Websense software activate a setting built into certain search engines so thumbnail images and other explicit content associated with blocked sites are not displayed in search results (see Search filtering).
When you have finished configuring Filtering settings, click OK to cache the changes. Changes are not implemented until you click Save All.
